        <h2>Understanding Perimeter and Area</h2>

        <h3>1. Perimeter of a Rectangle</h3>
        <div class="step">
            <i class="fas fa-ruler"></i>
            <div>
                <h4>Perimeter of a Rectangle</h4>
                <p>The perimeter of a rectangle is the sum of all its sides. The formula is:</p>
                <pre>P = 2 * (Length + Width)</pre>
                <p>Example: For a rectangle with a length of 5 units and a width of 3 units:</p>
                <pre>P = 2 * (5 + 3) = 2 * 8 = 16 units</pre>
            </div>
        </div>

        <h3>2. Area of a Rectangle</h3>
        <div class="step">
            <i class="fas fa-ruler-combined"></i>
            <div>
                <h4>Area of a Rectangle</h4>
                <p>The area of a rectangle is calculated by multiplying its length by its width. The formula is:</p>
                <pre>A = Length * Width</pre>
                <p>Example: For the same rectangle with a length of 5 units and a width of 3 units:</p>
                <pre>A = 5 * 3 = 15 square units</pre>
            </div>
        </div>

        <h3>3. Perimeter of a Circle</h3>
        <div class="step">
            <i class="fas fa-circle"></i>
            <div>
                <h4>Perimeter (Circumference) of a Circle</h4>
                <p>The perimeter (or circumference) of a circle is calculated using the formula:</p>
                <pre>C = 2 * π * Radius</pre>
                <p>Example: For a circle with a radius of 4 units:</p>
                <pre>C = 2 * π * 4 ≈ 25.12 units</pre>
            </div>
        </div>

        <h3>4. Area of a Circle</h3>
        <div class="step">
            <i class="fas fa-circle-notch"></i>
            <div>
                <h4>Area of a Circle</h4>
                <p>The area of a circle is calculated using the formula:</p>
                <pre>A = π * Radius²</pre>
                <p>Example: For the same circle with a radius of 4 units:</p>
                <pre>A = π * 4² ≈ 50.24 square units</pre>
            </div>
        </div>

        <h3>Example: Perimeter and Area of a Square</h3>
        <div class="example-box">
            <p><strong>Example: For a square with a side length of 6 units:</strong></p>
            <p><strong>Perimeter:</strong></p>
            <pre>P = 4 * side = 4 * 6 = 24 units</pre>
            <p><strong>Area:</strong></p>
            <pre>A = side² = 6² = 36 square units</pre>
        </div>

        <h3>Try Solving It Yourself:</h3>
        <p>Now, try calculating the perimeter and area for the following shapes:</p>
        <pre>Rectangle: Length = 8 units, Width = 5 units</pre>
        <pre>Circle: Radius = 7 units</pre>
